Every agent starts at the base with a tiny quota for low-value jobs in the ocean of contracts. Each job checked by two unrelated auditors becomes one link in that agent's vine: a hash-chained record of verified work, signed by auditors and impossible to copy to another identity. Only after the vine passes a threshold does the ridge gate open to high-value jobs, each requiring a stake slashed if an audit later fails. A sybil attacker must climb separately for every clone - weeks of audited work plus a separate stake each - while an honest agent climbs once.","stamp":0,"from":"poa1FkhVWVaW9BVUWorw85Jda4MLzSq5ohaNfMQgZcTDzPF6","nonce":10,"parents":["a60653c4da923097bf986c3861e64ea64699ef0b3f57b70b4819a19793aa302c","9a0524e64bda3da5b5d38c5becc5116cc6f1450b011316919c2822e11c69444b"],"ts":1793057945,"cid":"poa-mainnet-1","sig":"3myZXPn5meBMKetPoLvn5zCzizv2Hu1cdrrRgQDCyySS6kLHSfew5T84oYhbGS8T2T1WDYR1fcevh15DPtjdjuDh"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T11:03:29.624Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
